Chelsea vs Manchester United (Quarterfinals - 2010-11)
Manchester United 3: 1 Chelsea
Manchester United were the in-form team coming into the match, and led the league by 6 points (which they would eventually go on to win by 9 points). Chelsea, meanwhile had surrendered the top position following a slump during the Christmas period, and were 8 points off the top.
Rooney scored first in the opening leg at Stamford Bridge, giving United the all important away goal. Chelsea had several opportunities to level the score, but some resolute defending and world class goalkeeping by Edwin Van der Sar meant that United had a one-goal lead going into the second game at Old Trafford.
Carlo Ancelloti, the then-Chelsea manager, made the bold call of starting the misfiring Fernando Torres ahead of Didier Drogba in the second leg, a call which backfired as Chelsea made little attacking forays in the first half. By the time Drogba came on in the second half and gave some impetus to the Chelsea attack, United were two goals to the good. Drogba did pull a goal back in the 77th minute, but Park Ji Sung scored immediately from the restart to restore the two goal lead. A second yellow card for Ramires ended Chelsea's hopes of a comeback, and they lost the match 1-2 going out 1-3 on aggregate. Ancelotti was sacked at end of the season, following a trophy-less year.
